2 Claims.

This invention relates to a yarn carrier package. More particularly ithas to do with means for holding the yarn end on a carrier or bobbin sothat it will be readily accessible to an operator when the carrier is tobe placed on a frame or inserted in a magazine or in a shuttle.

The invention may be employed with a bobbin carrying a warp yarn as wellas one carrying a weft or filling yarn and the appended claims are to bedeemed as covering both uses.

In the operation of weft replenishing looms the weft carriers, orbobbins, are placed in magazines for successive discharge into a loomshuttle, and it is highly important that the end of the Weft thread oneach carrier be attached to a weft holder in order that the thread maybe held in position to be drawn into the thread eye of the shuttle onthe first pick after transfer. In charging the magazine each bobbin mustbe inserted in position for transfer, and at the same time the threadend must be attached to the weft holder. In the case of wound bobbinsgenerally heretofore employed, whether used in looms or in windingframes, the yarn end is left free and tends to cling closely to thewound surface. It may extend beyond the end of the bobbin or may lie atsome point intermediate the ends of the wound portion. This free end isdif'lcult to grasp quickly by reason of its usual closeness to the windand particularly so by reason of the fact that the operator has to lookcarefully to locate its position longitudinally of the wind. As aresult, portions of the wound threads are frequently broken or torn indetaching the free end by the operator.

One object of the present invention is to provide means for anchoringthe yarn end on the bobbin at a place where it may be easily located bythe operator, without taking time to examine each bobbin more or lesscarefully, and in such a manner as to enable the operator to disengagethe same quickly for attachment to a holder.

Another object of the invention is to provide in addition to the usualsingle, widely spaced final wind of the yarn along the surface of theclosely spaced winds a separated group of winds of the yarn to insure asufficient length for attachment to the holder without any unwinding ofthe closely spaced windings on the bobbin.

Another object of the invention is the provision of a yarn carrierpackage in which anchoring means is provided for the yarn end at a placeon the base of the bobbin or carrier in such a manner that the yarn endis drawn over the shouldered end of the base in position to be en- 4.1.

gaged readily without interference with the normal winding on thecarrier.

A further object of the invention is the provision of a yarn carrier orbobbin having the base so constructed as to provide a portion adapted toreceive a terminal winding of the yarn end and to serve as an anchoragetherefor.

A further object of the invention is the provision of an anchoring meansfor the yarn end on the base of the bobbin at an appreciable distancefrom the normal wind thus enabling the operator to detach the yarn endwithout the exercise of any particular care'as regards to the woundportion, since the yarn end is sufiiciently remote from the normal windto avoid interference therewith in its detachment.

Other objects and advantages of the invention relate to various improveddetails of construction and novel arrangements of the parts, as will bemore fully set forth in the detailed description to follow.

The best mode in which I have contemplated applying the principles of myinvention is shown in the accompanying drawing but this is to be deemedillustrative for it is intended that the patent shall cover by suitableexpression in the appended claims whatever features of patentablenovelty exist in the invention disclosed.

In the accompanying drawing:

Figure 1 is an elevational view of a portion of a winding frame, showingthe winding ring in a position in the formation of the usual wind and inanother position where a terminal winding is made after the applicationof a spaced wind overlying the usual wound portion;

Figure 2 is an enlarged view of a wound carrier or bobbin of a typewhich may be employed in carrying out the present invention; and

Figure 3 is a View of a replenishing loom shuttle, showing the positionof a weft carrier therein after transfer.

In the embodiment of the invention shown and described herein, Idesignates an element of a winding frame carrying spindles 2 and 3 uponwhich are mounted bobbins or carriers 4 and 5, supporting complete andpartial windings 6 and 1 respectively. Guides 8 and 9 are mounted on abar I!) in position to guide yarns H to ring travelers on winding ringsl2 and I3 for application to the carriers 4 and 5 respectively. Theposition shown of the winding ring I3 is such as would occur during thenormal and usual winding of the yarn upon the bobbin, while the positionshown of the winding ring I2 is that which it assumes after the closewind of the yarn has been completed, and a single widely spaced wind hasbeen made and the terminal windings are being formed. These respectivepositions of the winding rings are purely illustrative and it is to beunderstood that actually the rings are mounted on a continuous bar [4and all occupy like positions relative to the bobbin.

The invention resides in providing below the usual base I5 with theusual metal holding rings IS, an extended portion I! having one or moregrooves l8 thereon to receive the terminal yarn windings [9 after theapplication of the normal close windings 20 and the widely spaced returnwinding 2|, which are made on the yarn carrying shaft portion 22 of thebobbin.

The base l5 of the bobbin or weft carrier is shown as of a diametermaterially greater than that of the shaft portion 22, as well assomewhat larger in diameter than the reduced portion 20a of the normalwinding 20 which tapers toward the base. At the transition from theshaft portion 22 to the full diametrical portion I5 there is provided ineffect an outwardly projecting shoulder 23 over which the yarn ll passesafter forming the spaced return winding 2|. The yarn then passes overthe outstanding surfaces of the metal rings l6 thus positioning the yarnII in slightly raised relation with the usual base portion l5, so thatthe yarn Il may be readily located and quickly broken at this point ifdesired. The breaking of the yarn where it passes over the shoulder andover the metal rings insures against injury to the normal winding 20.

To hold the yarn across the shoulder 23 and the metal rings [6, theinvention provides that after crossing these rings the yarn will beWound several times about the extension IS in one or more of the groovesI8. Such turns of the yarn in a groove hold it in place and it iscontemplated that, if the operator prefers, these terminal windings maybe readily slipped downward over the bottom end of the bobbin and usedas a portion of the lead to the weft holder of a magazine. But whetherthese terminal windings are so used or are broken off and thrown away,the yarn end is readily at hand and the rapid winding 2| may be easilyunwound to provide the lead to the weft holder.

The replenishing loom shuttle 24 is provided with a bobbin receivingrecess 25 and carries the usual transversely grooved spring arms 26 forgripping the metal rings I6. A thread block 21 is carried by the shuttlein position to receive the weft thread during or immediately aftertransfer and guide the same into the thread eye 28 on the first pickafter transfer.

It will be seen that the present invention is capable of and adapted tofacilitate greatly the operation of charging a loom magazine or awinding frame by rendering the yarn ends of the carrier packages easilyaccessible to the operator in such a manner as to permit theirdetachment without injury to the main winding.

I claim:

1. In a yarn carrier package, a carrier having a base with a shaftportion extending therefrom on which the yarn is normally wound, holdingmeans carried by the base for supporting the carrier within a shuttlebody, and a grooved surface on the base located beyond said holdingmeans and opposite to said shaft portion, for receiving terminal yarnwindings to form an anchorage for the yarn end.

2. In a yarn carrier package, a carrier having a shouldered base with ashaft portion extending therefrom in one direction upon which the yarnis normally wound, said base having a portion extending in the oppositedirection with grooves on its surface remote from said shaft portionupon which said grooved surface terminal windings of the yarn are madeto form an anchorage for the yarn end after the completion of the normalwinding on the said shaft portion of the carrier.
